165
Check code name
[F07] / [18]
(d07 / AI-NET)
Check code name
TL sensor error
Cause of operation
TL sensor Open/Short
This error code means detection of Open/Short of TL sensor. Check disconnection of circuit for connection of connec-
tor (TL sensor: CN521, White) and characteristics of sensor resistance value.
(Refer to Outdoor unit temperature sensor characteristics.)
If sensor is normal, replace outdoor I/F P.C. board.

TO sensor error
Cause of operation
TO sensor Open/Short
This error code means detection of Open/Short of TO sensor. Check disconnection of circuit for connection of
connector (TO sensor: CN507, Yellow) and characteristics of sensor resistance value.
(Refer to Outdoor unit temperature sensor characteristics.)
If sensor is normal, replace outdoor I/F P.C. board.

Indoor TA sensor error
Cause of operation
TA sensor Open/Short
This error code means detection of Open/Short of TA sensor. Check disconnection of circuit for connection of connec-
tor (TA sensor: CN104, Yellow) and characteristics of sensor resistance value. (Refer to Outdoor unit temperature
sensor characteristics.)
If sensor is normal, replace indoor P.C. board.

TS1 sensor error
Cause of operation
TS1 sensor Open/Short
This error code means detection of Open/Short of TS1 sensor. Check disconnection of circuit for connection of
connector (TS1 sensor: CN504, White) and characteristics of sensor resistance value. (Refer to Outdoor unit tem-
perature sensor characteristics.)
If sensor is normal, replace outdoor I/F P.C. board.
